Automatic circuit breaker ETI ETIMAT 10 3P 10A D 10kA (2155714)

ETIMAT 10 from ETI is an automatic circuit breaker designed for protection of electrical lines against overload and short circuit in AC power systems. With three poles, it is intended for three-phase circuits where simultaneous switching and protective disconnection of all phases is required. The rated current is 10 A, which makes the device suitable for lines with relatively low operating load, while the D tripping characteristic allows it to be used in circuits with high inrush currents, such as installations where connected equipment creates short-term current peaks during start-up. The breaking capacity of 10 kA indicates that the breaker is able to disconnect high short-circuit currents, which is important for distribution boards and circuits with increased protection requirements. The device operates in AC networks with a rated voltage of 400 V and a frequency of 50/60 Hz. A rated impulse withstand voltage Uimp of 6 kV means the breaker has resistance to short-duration voltage surges that may occur during switching operations or due to external electrical disturbances. The model supports conductors with a nominal cross-section from 1 mm² to 25 mm², which simplifies integration into different wiring schemes and makes installation more flexible. Compliance with IEC/EN 60898-1 and IEC 60947-2 confirms that the device meets the requirements for low-voltage automatic circuit breakers in terms of operating parameters and protection characteristics. This breaker is used in residential, commercial, and industrial electrical installations where automatic line disconnection is needed in the event of abnormal current conditions. It is suitable for distribution boards, group circuits, and three-phase loads that require coordinated protection and isolation. The combination of a 3-pole design, 10 A rating, D curve, 10 kA breaking capacity, and 400 V AC operation makes the ETIMAT 10 a functional solution for circuit protection and controlled switching in low-voltage networks.
